improvements in poultry devices and particularl-y to brooders. Y Y

One Object of the invention is to provide a device of this character wherein the chicks will be kept warinwithout the use of artificial heating means, which means throws off gases injurious to the chicks. Y

Another object is to provide a device of this character which is readily adjustable for the purpose of increasing the hover space, as the chicks becomelarger.

Another object is to provide a device of this character which can be easily and quickly taken apart for cleaning purposes.

Other objects and advantages will `be ap- Y parent from the following description when taken in connection with the accompanying drawing.

In the drawing: Y

Figure 1 is an elevation of a brooder made inV accordance with `the invention.

Figure 2 is a vertical sectional view taken centrally through the brooder on the line 2 2 of Figure 1. Y

Figure 3 is a horizontal sectional view on the line 3-3 of Figure 1.

Referring particularly to the accompanying drawing, A represents the inside or hover section, and B the outside or enclosing section of the brooder, the former being formed from comparatively heavy cardboard, while the latter isy preferably formed j from galvanized meta-l.

The inside section A includesy the circular wall 10,v formed from a singleV length of card-board having the longitudinal series of openings 11 adjacent itsfupper edge, and

an angular notch 12, cut in the center of the lower edge, this latter notch `forming the doorway through which the chicks enter the hover chamber. Carried by one end of the wall 10 is a transverse strip 13 beneath which the other end 0f the Wall 1S arranged to be disposed, a wire hook 14 being carried by the last named end to secure the ends of` the wall against movement from the adjusted position. By means ofthis adjustment the diameter of the space enclosed by the wall 1() can be made larger or smaller according to the number of chicks, or the size of the chicks. Supported on the upper edge 'of the wall 10 is a conical roof 15 the i same having an opening 16 in its apex, and

alongitudinal window 17 in one side near the apex. Formed in the roof 15, in lines radiating from the apex toward the peripheral edge thereof, are the series of open- `ings 15 through which are arranged to be inserted pins 16 which engage outwardly of the circular wall 10 to maintain the roof in position, and to assist in holding the wall. By kthis arrangement, when the wall 10 is adjusted to increase or diminish its diameter,thepins 16 will be moved into the appropriate openings 15, as will be readily understood. Y i rl`he Hoor `18 is preferably formed from a disk of metal, and on this Hoor the hover chamber is adapted to' rest.A y c Also resting on the floor 18, in concentric spaced relation outward of the wall 10 is the metal wall19. This wall also has the longitudinal series of Ventilating openings 20 adjacent its upper edge, and the doorway opening 21 in the center of its lower edge.

Theends of the wall 19 are rigidly secured tween the walls 10 and 19, the air of which is cooler than the air within the hover f chamber. .j

Disposed on the upper edge of the wall 19 is a conical roof 24 having an upwardly extending tubular wall in the apex thereof, as shown at 25, said wall 25 being formed with a circular series of ventilating openings 26. VADisposed in encircling relation around the wall 25, and also provided with a series of openings 27, arranged to register with the openings 26, is a wall 28, having a dome-shaped cover V29 secured to its upper @dse By means af .t11isva1128, more Vor less air 1na57 he exhausted through the rooi1 24 and pass through the opening in the apex oi the rool of the hrood or hover chamber, While fresh air enters through the openings l1 and 20. l

From the foregoing it will he understood that When the chicks are veqy sinall, the inner Wall l0 is contracted to its smallest diameter, and as the chicks grow, the Wall is permitted to expand, making the space enclosed thereby larger, until the Wall lO hears against the outer Wall 19, When the chicks are large enough to mingle with the other chickens.

That is claimed is:

l. A hrooder comprising an inner and an outer housing, cach of the housings having a circular Wall and a conical roof, the Walls and roots having inlet and outlet openinos, the latter openings ot the outer root1 being regulatahle, iight entrance means in the said roofs, aligned entrance lopenings in the walls of the housings, and a tunnel ineinher connecting the entrance openings and extending hetiveen the Walls otl the housings.

A broeder comprising an inner and an outer housing, the root' ot the outer housing 1oeing provided Wit-h a tubular Wall having openings therein, a movable cover for the tubular Wall, said cover being formed with a series of openings positioned to register with those in the tubular Wall, the roof of the inner housing' being provided with a series of openings7 and pins adapted for selective insertion Within these openings and arranged to contact With the Wall of the inner housing;

3. fr hrooder comprising an inner and an outer housing, each of the housings having a circular Wall and a conical root', the root of the outer housing being provided with an upwardly directed tubular Wall, the walls and roots having inlet and outlet openings, a movable cover for the tuliular Wall, said cover being provided with a series of openings positioned 'for selective registryY with those in the said tubular Wall, entrance openings in the walls ot the housings, and :i tunnel member connecting the entrance openingsl and extending therehe tween.

Ll. A brooder comprising an inner and an outer housing, each ot the housings having a circular Wall and a conical root, the Walls and roofs having inlet and outlet openings, the latter openings of the outer rootl heing regulatable, supplemental openings `lorined in the root' ot the inner housing, pins adapted for selective insertion Within the last mentioned openings and arranged to contact with the outer surface of the Wall ot the .inner housing'v` entrance openings in the walls ot' the housings, and a tunnel member connecting the entrance openings and extendino' therebetween.

In testimony7 whereof, I atli; my signature, in the presence ol tivo Witnesses.
